修改seata/conf/application.yml，参考application.explame.yaml

然后执行seata-server.sh，注册到指定的namespace下

在nacos上面创建事务组

service.vgroupMapping 前面固定的格式，后面加**.order-tx-group**。后面这个可以是client端的spring.application.name的value值，但是它们拼接起来要和nacos的添加的配置文件要保持一致

对应客户端的spring.application.name

构建seata-client端

1. 上面已经再nacos配置的配置了service.vgroupMapping.xxxxx-group

不用使用下划线可能会用问题

3. 修改application.yml

4. 主启动类 其他业务类小编没有写，家人么可以自己发挥

package com.test;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.transaction.annotation.EnableTransactionManagement;

@SpringBootApplication
@EnableDiscoveryClient
@EnableTransactionManagement
public class App {

    public static void main(String[] args) {
        SpringApplication.run(App.class,args);
        System.out.println("启动成功");
    }
}

AT模式sql脚本

SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;

-- ----------------------------
-- Table structure for undo_log
